sterol methyl transferase2 [Zea mays] e-value=2e-23 (G10 is 2e-24) also match with24-methylene lophenol C24(1)methyltransferase [Oryza sativa Japonica Group], e-value=1e-22, and also match with sterol-C-methyltransferase [Arabidopsis thaliana],e-value=3e-15. So it seems like a methyltransferase gene, at least part of the gene.
